My invention relates to floor Constructions, principally concrete floor constructions, whereinvarious) newresults are attained by new and novel means 1 y An object of my invention is to provide a concrete floor that may have'concrete ribs, and having a nished ceiling, that] may be of plaster, concrete or lother material and wherein lath heretofore used to support such nished ceiling is 'dispensed with.v

' Another object of my invention is to produce a molded ceiling and concrete floor structure wherein the present 'expense incident to hanging of lath and the strenuousV laborincident to plastering the ceiling may be eliminated.

Another object of my invention is to'provideconcrete floors and the likewherein the wiring conduits,4 pipes `for other purposes,

etc., can'be positioned and arranged with a minimum of time and effort and in'an'eX peditious manner.

Another object of my invention is 'to provide k'simple and economical means forati taining the stated and other objects;

` These -and other'objects are attained 'by the means described herein and disclosed inv the accompanying drawings,in which:`

be molded, andwhich on solidifying may beV bonded, by any agencies or means to a `floor capable ofl formation while in'a plastic con-V dition, for example concrete, that is then formed or molded upon or above the ceiling;

In Fig. 1 is shown-onelform'of my inven tion, wherein a temporary flooring (intenter-l inglO is' supported by shoring 11. On the upper 'surface on the temporary flooring'l() are positioned in spaced relation ja number of casings12 for rforming concrete keys 13. Thev casings 12 are Vprovidedl with open ends 14 and' 15 and'may-be givenfany'desired form, for 'examplea truncated cone 16er a truncated pyramid 17 or the'like; Again the casingmay take the form of an elongated channel 18 'open `at its top and extending'the length of' thejiioor to be constructed.v The sidesof the channel, 'truncated cone,` and` truncated pyramid converge upwardlyf rlhe casings'l, 1'( and 18 may be provided with flanges 19 rthrongh which a securing 'means may pass for securing thejeasings to the vtems poraryv flooring ,10, Any' other suitable means may be" providedl 'for retaining the casing in positionl" `The"`ca`s ing's '12 'are positioned lor spotted, as -shown, in longitudinal and lateral alignment having the larger and contacting the temporary iiooring 10 This structure Vprovides a series ofpockets having theirlower ends sealed by the flooring 10 andi upper ends open to receive the plastic concrete'. lllhehoasingsV are" positionedVv as shown at Fig.' 1, at the lower end of the -concrete beams 20. The concretefwhen poured enters the open ends M ofthe' leasing, 12 land forms keys integral with the beams 20. After thec'asings have been' positioned a cementitiousfceiling'material 21, for example plaster, concrete,` gypsum composition,y etc., is pouredon the upper surface of the flooring 10 andaround thejoutside of the'casings 12E This silbstan'ce:21'beeonies`the vinished ceiling of the room below. After this first cementitious layer has set it may be walked upon by the workmen without damage or injury to the ceiling. The temporary centering is retained in position. The workmen may arrange the domes or tiles 22 upon the upper surface 23 of the ceiling 2l between which domes the beams 2O are to be formed. After the domes 22 have been positioned a second layer of cementitiousor other material, for example, concreta, for the floor 24, may be poured. Some of the concrete enters the open ends 14 of the casings l2 and forms concrete keys 13 for bonding the ceiling 2l to the floor 24.

The modified structure shown in Fig. 2 dispenses with the reinforcing beams 20 but is laid in the same manner as above described. ceiling 2l has set theworkmenmay walk thereon for positioning the reinforcing bars 2,5, electrical wire conduitsv 26, waste pipes 2 etc.

In Fig. 5 I have illustrated a modified form of casing having corrugated inclined sides 28 and 29. The corrugated sides afford agreater supporting surface. The cementitious vmaterial is adapted to enter the depressions on opposite surfaces of the sides and affords a substantial lock or bond between the cementitious materials and the casing.

It should be noted that lathing is not used for supporting the ceiling 21, although it is readily evident that in some buildings it may beV desired'to use reinforcing materials, for example, iron bars or ybars of steel or other material, fabricated reinforcements in the nature of metallic webbing or metal lath. Further, having the ceiling formed before the temporary flooring is removed dispenses with the time necessary to have plasterers put up a plaster ceiling. 1With this method of construction the cost is materially reduced because of the materials and labor dispensed with. lVorkmen may `work quickly and without impediment upon the precast ceiling while engaged in positioning the reinforcing bars for the concrete beams and floor'slabs, and conduits and pipes for electric wires, water and waste.

VThe forms disclosed in Figs. 6 to 10 inclusive suggest a few of the possible variations that maybe employed. For example, some of the forms may be imbedded or spotted in the plastic ceiling after the ceiling has been poured instead of being mounted on the temporary centering, see Figs. 9 and 10. Other'forms may have more point contacts upon the temporaryr centering, see Fig. 6. Other forms are adapted to contact the lateral edges of the tiles or domes and thereby preclude spreading and collapsing of the tiles, see Figs. 7 and 8.'Y Other domes may be'provided with grooves, beads or other indicia for indicating the height or After the first cementitious slab orY thickness to which the ceiling slab should be formed, see Fig. 6. In one of the simplest forms of my invention a channel may be embedded in the ceiling slab, the ends of the legs projecting above the ceiling slab and serving to receive between them the edges of the tiles or domes. Many of the enumerated features of the individual forms referred to may be consolidated in a single means or structure.

lVhat I claim is:

l. In a floor and ceiling construction the combination of a concrete floor having concrete beams, a poured in place ceiling slab, hollow elements embedded -in the slab and providing downwardly diverging pockets to receive integral concrete keys formed at the base of the beam for supporting the ceiling.

2. In a floor and ceiling construction the combination of a Vpoured in place continuous cementitious ceiling slab, hollow pocket forming elements embedded in the ceiling slab, supporting beams, and keys formed integral with the beams filling the pockets and supporting the ceiling..

3. In a floor and ceiling construction the combination of a cementitious ceiling slab, selectively positionable means for forming dove-tailed openings in the ceiling slab, and a second cementitious slab entering the openings in the ceiling slab and bonding said ceiling slab to the second cementitious slab.

t. In a floor and ceiling construction the combination of a concrete floor, concrete beams formed integral with the floor, a ceiling slab, hollow metallic pocket forming means carried by the ceiling slab, and depending concrete keys formed on the beams entering the pocket forming means and bonding the Vbeams and the ceiling slab.

5. In 'ai floor and ceiling construction the combination of a poured in place cementitious slab providing a finished ceiling face and having pockets formed in its upper face and a cementitious structural door mass cast upon said upper face of the ceiling and entering the pockets to form integral keys wherebythe ceiling is suspended from the floor.

6. A floor and ceiling construction come prising la precast finished ceiling, means in the bodyv of said ceiling providing hollow open topped pocketstherein, and a structural cementitious floor cast upon said ceiling and having integral portions thereof filling the pockets in the ceiling to `form keys for suspending said ceiling. i

A7. The method of building comprising erecting a temporaryV support, placing pocket molding means thereon, casting a continuous cementitious slabon the support and aroundthe pocket forming Vmeans to provide hollow pockets in the slab, allowing said cast cementitious slab to harden, then Y casting a second structural cementitious slab over the first slab and filling the pockets in the first slab, then' allowing the second slab to set and removing the temporary support.

8. The process of building construction Comprising pouring a cementitious ceiling slab With a finished lower face and provided with openings in its top face, permitting said slab to harden, forming a cementitious structural Hoor slab over the ceiling slab and lling the openings in the ceiling With the material of the floor slab to bond the ceiling to the floor.
